INSECT-GUARD FOR 'WINDOWS.

SPECIFICATION formingpart of Letters Patent No. 7 22,499, dated March 10, 1903. Application filed October 9, 1902. Serial No. 126,559. (No model.)

To all whom it may concern.-

Be it known that I, ELLSWORTH P. DOTY, a citizen of the United States, residing at Fairhaven, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Insect-Guards for Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

When one sash or the other of a window is raised or lowered for the insertion of a flyscreen, it is well understood that insects enter through the space left between the lower rail of the upper sash and the glass of the lower. The object of my invention relates to a guard automatically adj usting itself to close this space and it consists, essentially, of arms secured to the lower rail of the upper sash, levers journaled on said arms carrying on their upperends a guard-plate of adjustable length to fit any ordinary width of window, springs engaging with the levers to hold the guard-plate out of engagement with the glass in normal position, and antifriction-rollers on the lower ends of the levers to engage with the side rails of the lower sash and swing the guard-plate in against the glass thereof to close the opening when one sash or the other is partly opened; but when fully opened the rollers pass below-and disengage themselves" from the lower sash, and the springs swing the guard-plate out, permitting the sash to pass. When the sashes are returned to partly or wholly closed position, the rollers again engage with the said rails, and the plate is again swung in against the glass.

My invention will be understood by reference to the drawings herewith, in which the reference-numerals of the specification indicate the corresponding parts in all the figures.

Figure I is an elevation of upper and lower sash with my invention applied thereto. Fig. 11 is a side elevation of my invention with the sash in section and arranged in wide-open position. Fig. III is an elevation corresponding to Fig. II, showing the guard-plate also in section and the lower sash partly raised. Fig. IV is a top plan view of the guard-plate. Figs. Vand VI are respectively front and side bent to clear the lower rail 5 of the lower sash and carrying rollers 6 to engage with the side rails 7 7 and their upper portions preferably straight to engage with sockets 8 8 of the end pieces 9 9 of the guard-plate, fitted to slide in channels 10 10 on the edges of the center piece 11, whereby the length of the guardplate may be adjusted substantially to any width of window. The guard-plate is secured to the under surface of the lower rail by screws engaging in slots 13, permitting a suflicient movement of the plate in and out. Spring 15 may be suitably arranged, as on pintle 16, to engage with the levers and arms and swing the guard-plate out into the normal position. Integral stop 17 may be provided on the upper portion of the lever to engage with the arm and limit its movement. One or more notches 18 may be formed in the center piece 11 to fit muntins where the glass of the sash is in small panes, but closed by plate 19 with a single-pane sash.

My guard-plate is light, simple, and economical to construct, all parts being of stamped metal, effective in operation, and easy to adjust. It is first regulated to the width of the window and then is set in the bottom of the window and the amount of stroke ad justed to adapt it to the thickness of the rails. The guard-plate is then secured in position with the arms carrying the levers in position at each end and the upper ends of the levers sprung into engagement with the sockets on the ends of the end pieces.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an insect-guard, the combination with supporting-arms secured to the lower rail of the upper sash, levers j ournaled on the arms, aguard-plate on the upper ends of the levers, rollers on the lower ends of the levers to en- ICC gage with the lower sash and swing in the guard-plate, and springs suitably arranged to swing out the guard-plate.

2. In an insect-guard, the combination with supporting-arms secured to the lower rail of the upper sash, levers journaled on the arms, a guard-plate of adjustable length on the upper ends of the levers, rollers on the lower ends of the levers to engage with the lower sash and swingin the guard-plate and springs suitably arranged to swing out the guardplate.

3. In an insect-guard, the combination with arms to be secured to the lower rail of the upper sash, levers journaled to the lower ends of said arms, a guard plate of adjustable length having cross-slots and fitted to the upper ends of said levers, screws engaging with said slots to secure the guard-plate on said lower rail, rollers on the lower ends of said levers to engage with the lower sash and swing in the guard-plate, and springs suitably arranged to swing out the guard-plate.

4. In an insect-guard for windows, the combination with the upper and lower sash, of arms secured to the lower rail of the upper sash, levers journaled to the lower ends of said arms, a guard-plate composed of a center piece having channels on its said edges and end pieces fitted to said channels, and provided with sockets to engage with the upper ends of said levers, screws fitting crossslots in the center piece to secure the guardplate to the lower rail of the upper sash, antifriction-rollers on the lower ends of the levers to engage with the side rails of the lower sash and swing the guard-platein, and springs suitably arranged to engage with the arms and levers and swing the guard-plate out.

5. In an insect-guard for windows, the combination with the upper and lower sash, of downwardly-depending arms secured to the lower rail of the upper sash, levers journaled to the lower ends of said arms, a guard-plate fitted to the upper ends of said levers and provided with notches to fit the muntins, plates fitted to slide on the guard-plate and close the notches for muntinless windows, screws fitted to cross-slots in the guard-plate to secure it on the lower surface of said lower rail, antifriction-rollers on the lower ends of the levers to engage with the side rails of the lower sash to swing the guard-plate in, and springs suitably arranged and engaging with the levers and arms to swing the guard-plate out.

6. In an insect-guard to close the space between the sash of windows, the combination with the upper and lower sash, downwardlydepending, supporting-arms secured to the lower surface of the upper sash at each end, levers having straight upper portions and downwardly-curved lower portions journaled to the lower ends of said arms, end pieces having narrow, socketed ends engaging with the upper ends of said levers, a center piece having channels on its sides to engage with said end pieces, screws fitted to cross-slots in said center piece to secure it in position on the lower surface of the upper sash, antifriction-rollers on the lower ends of the levers to engage with the side rails of the lower sash to swing the guard-plate composed of the end pieces and the center piece, in to close the opening, springs arranged on the journalpintles of the levers and engaging with the arms and levers to swing the guard-plate out permitting the sash to pass, and stops on the levers to engage with the arms.

7. In an insect-guard, the combination with levers suitably journaled to the lower rail of the upper sash and having downwardly-extending lower ends adapted to engage with the lower sash and swing in the upper ends of the levers, of a guard-plate on the upper ends of the levers and springs suitably arranged to swing out the guard-plate.

8. In an automatically-operating insectguard for windows, the combination with supporting-arms secured to the lower rail of the upper sash, of levers journaled on the arms, a guard-plate on the upper ends of the levers, and springs suitably arranged to swing out the guard-plate, the lower ends of the levers being adapted to engage with the lower sash and swing in the guard-plate.

9. In an automatically-operating insectguard for windows, the combination with supporting-arms secured to the lower rail of the upper sash, of levers journaled on the arms, a guard-plate of adjustable length supported on the upper ends of the levers, and springs suitably arranged to swing out the guard-plate, the lower ends of the lovers being arranged to engage with the lower sash and swing in the guard-plate adjacent to the glass of the lower sash.

10. In an insect-guard for windows provided with sliding sashes, the combination with supporting-arms secured to the lower or inner rail of one sash, levers journaled to the lower or inner ends of said arms, a guardplate of adjustable length provided with cross-slots and fitted to the upper or outer ends of said levers, screws engaging with said slots to secure the guard-plate on the rail of the first sash, said levers being provided with inwardly-extending ends arranged to engage with the second sash to swing in the guardplate against the glass of said second sash, and springs suitablyarranged to swing out the guard-plate.

In testimony whereof I affix myv signature in presence of two witnesses.
